Nationwide – via National Casualty Company – has filed a rate and rule update for its Modular Pet Insurance program in North Carolina, seeking an overall 8.2% average rate decrease. The changes apply to new business effective July 2, 2026, and renewals effective August 27, 2026.

The program currently includes 4,313 in-force policies in North Carolina and approximately $2.8 million in written premium. While the overall impact is a decrease, the filing reflects meaningful variation by coverage, with some segments increasing and others declining.

A central element of the filing is the introduction of a generalized additive model (GAM) to support pricing. The company is also adding gender and tenure as rating variables, alongside updates to breed, age, utilization tier, and ZIP code factors, to better align premiums with expected loss experience.

Coverage-level indications diverge across the modular structure. Accident and wellness coverages show upward pressure, while illness, congenital or hereditary, cruciate, behavioral, and prescription food coverages trend downward, producing the net reduction. The filing targets a 72.1% permissible loss ratio, with expense and profit provisions consistent with prior filings.

Nationwide noted the product was soft-launched in 2021 and expanded more broadly in mid-2023, leaving portions of the book with limited credibility. As a result, the company relied on state and countrywide experience and CPI-based trend assumptions rather than internal trend development.
